Go to the library or a car parts store and look in Chiltons Auto Repair manual. If the picture isn't good enough, try Haynes or Motors. When you get a carburetor rebuild kit they usually have line drawings of the exploded carb- better than a photo. To rebuild the carburetor, you take off the top and replace all the gaskets, seats,diaphragms, needles, and float, then put it back together. It's like a three dimensional puzzle. Take your time and don't mix things up. Read the instructions and keep them close to you as you work on a brightly lit table. I'd do it in the kitchen but my wife would have a big fit. Keep everything as cleanas an operating room. Lots of folks soak the carb in carburetor dip before working on it.
